Title: Formation of end face partial reflection film for semiconductor laser device
Inventor: SHIGIHARA KIMIO
IPC: H01S5/00
Filed: 1988-10-03
Abstract: PURPOSE:To enable the application of a resist film onto an active layer of a semiconductor laser device always and also the formation of an end face partial reflection film at a high yield rate on the semiconductor laser device by a method wherein a film is provided to the surface of the laser device near to the active layer for increasing thickness. CONSTITUTION:A film 5 used for increasing thickness is provided to the surface of a semiconductor laser device 1 at least close to an active layer 2, then a resist 3 is applied onto an end face 4 where the active layer 2 of the semiconductor laser device 1 is provided, and then the resist 3 is patterned for the formation of an end face partial reflection film. For instance, a glycol phthalate film 5 is formed on a wafer 10 for which a wafer process has been done, and then the wafer 10 is cleaved into bars. When a resist film 3 is applied onto the end face of a bar-like semiconductor laser device 1, the resist film 3 is applied even on the active layer 2 through the presence of the glycol phthalate film 5 applied for increasing thickness. Therefore, an end face partial reflection film can be formed through a lift-off process performed thereafter at a high yield rate.

IPC: G05D3/00
Filed: 1987-10-05
Abstract: PURPOSE: To obtain a mechanism with a high stiffness against outer force by arranging two actuators so that forces in opposite directions can operate. CONSTITUTION: Piezoelectric actuators 71 and 72 are provided at both sides of a central protrusion 51 of a fixed rigid body part 1. The other edges of piezoelectric elements 71 and 72 are connected to protrusions 61 and 62 of each rigid body part 2. The rigid body parts 1 and 2 are connected by elastic flat plates 3 and 4. When voltages V1 and V2 with mutually opposite polarities are applied to the piezoelectric elements 71 and 72, one of the piezoelectric elements 71 and 72 is extended and the other shrinks, thus slightly moving the rigid body part 2 in reference to the rigid body part 1. When either outer force f1 or f2 is applied to the rigid body part 2, it is applied to either the piezoelectric element 71 or 72 as a compression force.  The piezoelectric element has a large stiffness against the compression force, thus achieving a mechanism with a large stiffness against both outer forces f1 and f2 .

Title: Flip-flop circuit
Inventor: HAYASHI HIDENORI
IPC: H03K3/037
Filed: 1984-11-27
Abstract: PURPOSE:To obtain a stable logical output without oscillation by adding an AND circuit to an edge trigger RS-FF circuit. CONSTITUTION:After an output of a T-FF circuit 8 is inverted with a delay time (t) based on the operation delay, a non-inverting output Q is released and an inverted output Q' transits to an H level state as a pulse G22. In this case, an output of an AND circuit 10 keeps the H level while a set input S and a reset input R exist at the same time. Thus, a trigger input T of the T-FF circuit 8 is regulated by the output and the output state of the FF circuit 8 keeps the rest input state so long as a normal set input is not given. Thus, a stable logical output without oscillation is obtained. The operation above is attained similarly when the reset input R transmits to the set input S and a stable logical output is obtained.
